Planning for Storm Exceedance in Development Sites
Development plans can designate areas within or near housing or economic development sites that would preferentially flood during extreme weather events, thereby protecting buildings while enhancing biodiversity.
Development plans can reduce flood risk to vulnerable development (existing or proposed) through planning for storm exceedance. For example, within a site zoned for housing or economic development, the plan may, if appropriate, designate areas within or close to the site that could preferentially flood during extreme weather events, thereby reducing or avoiding flood risk to buildings whilst at the same time enhancing biodiversity.
